Some Egg Quality Characteristics and Hatching Performances of Leghorn Hybrids

Abstract

This study examined the hatchability performance of the offspring and some egg quality characteristics, which will be obtained from crossing Leghorn breed chickens and five different genotypes. The study's experiment was carried out in the Prof. Dr. Hümeyra Özgen Research and Application Farm in Selcuk University. In the present study, which was designed to have one male and twelve females belonging to each genotype, a total of 186 eggs from each flock were examined. No adverse results were found in the incubation results of the crosses made with our local breed Denizli and Araucana, Brahma, and Cornish breeds, whose breeders increased locally. When egg quality characteristics were examined, the difference in egg weight between F1 genotypes was insignificant and ranged between 46.91-51.54 g on average. When the F2 generation was investigated, egg weight differed between genotype groups, and the average weights ranged between 57.6-67.14 g. In addition, the effect of genotype on egg shell strength values were found to be significant. In addition, the effect of genotype on egg shell strength and shell weight values were found to be significant. However, the effect on the Haugh Unit and yellow height were insignificant in the same generation. As a result, hybridizing genotypes with low yield performance with commercially important genotypes could provide a genotype for alternative production systems for future generations.

Leghorn Melezlerine Ait Bazı Yumurta Kalite Özellikleri Ve Kuluçka Performansları

Abstract

Bu çalışma Leghorn ırkı tavuklar ile beş farklı genotipin melezlemesi sonucunda elde edilecek yavruların kuluçka performansı ve bazı yumurta kalite özelliklerini incelemek için yapılmıştır. Çalışmanın deneyi Selçuk Üniversitesi Prof. Dr. Hümeyra Özgen Çiftliğinde gerçekleştirildi. Her bir genotipe ait bir erkek yirmi dişi hayvan olacak şekilde planlanan çalışmada toplamda her sürüden 186 yumurta incelendi. Yerli ırkımız olan Denizli ve lokal olarak yetiştiriciği artan Aracuana, Brahma, Cornish ırkları ile yapılan birleştirmelerde kuluçka sonuçlarında olumsuzluk bulunmamıştır. Yumurta kalite özellikleri incelendiğinde ise F1 genotipler arasında yumurta ağırlığı bakımından farkın önemsiz olduğu ve ortalama 46.91-51.54 g arasında değiştiği tespit edildi. F2 kuşağı incelendiğinde ise yumurta ağırlığının genotip grupları arasında farklılık gösterdiği ve ağırlık ortalamalarının 57.6-67.14 g arasında değiştiği tespit edildi. Ayrıca aynı kuşakta genotipin kabuk mukavemeti ve kabuk ağırlığı değerlerine etkisi önemli, Haugh Unit ve sarı yüksekliğine etkisi ise önemsiz bulundu. Sonuç olarak, düşük verim performansına sahip genotiplerin ticari önemi olan genotiplerle melezlemeleri gelecek nesiller için alternatif üretim sistemlerine bir genotip kazandırılabileceği sonucuna varıldı.
